Title: Optical pickup
Inventor: KENMOCHI NOBUHIKO
IPC: G11B11/10
Filed: 1987-07-06
Abstract: PURPOSE:To simplify constitution, and to make a device small, light and in addition, low-cost by separating a reflected light from a record carrier into two polarized components orthogonal with each other by a double refraction prism, and detecting them by two photodetectors. CONSTITUTION:The light flux of a laser light source 1 is converged on the record carrier 6, and its signal light is made incident on the double refraction prism 7 by a polarizing beam splitter 3. The prism 7 separates it into beams, which have polarization planes, parallel and perpendicular with/to a plane, made by an optical axis and the incident light, and emits them at different angles so as to be made incident on the photodetectors 10a, 10b, and the difference between the outputs of them is taken, then a magneto-optical signal strong against a light quantity variation noise, is detected by a differential operator 11. Accordingly, the light can be detected by being divided into two optical pathes through simple constitution, and the number of parts an the assembling manhour can be reduced, thereby an optical system can be made small.

Title: Current constriction type light-emitting diode
Inventor: KATO TOSHIHIRO
IPC: H01L33/44
Filed: 1988-07-06
Abstract: PURPOSE:To improve the efficiency of light extraction, and to prevent the leakage of operating currents by forming current constriction layers inhibiting operating currents with the exception of specified conduction regions between a second clad layer and an active layer and/or between the second clad layer and an upper electrode. CONSTITUTION:An electrode 26 is shaped onto an insulating film 24, and brought into contact with a contact layer 20 in a peripheral section in an opening 22. Consequently, operating currents flow from the electrode 26 to the contact layer 20 within the specified range of the opening 22, and the passage region of operating currents reaches to an electrode 30 through a second clad layer 18, an active layer 16, a first clad layer 14 and a substrate 12 while being slightly spread. Since the contact layer 20, the second clad layer 18 and the active layer 16 are made extremely thinner than the substrate 12 at that time, the conduction region of the active layer 16 is approximately equalized to the opening 22. Accordingly, the insulating film 24 functions as a current constriction layer, a light-emitting section in the active layer 16 is scaled down, and the efficiency of light extraction is improved while the leakage of operating currents can be prevented.

Title: Infrared ray lens
Inventor: SHINOHARA KOICHI
IPC: G02B13/14
Filed: 1985-08-01
Abstract: PURPOSE:To obtain a high performance infrared ray lens whose full length is short and whose aperture efficiency is set to 100% up to its periphery by specifying an overall system, the focus distance of the 1st lens, the radius of curvature of the i-th lens plane from an object side and the relationship between of lens planes in terms of the infrared ray lens composed of 3 groups X 3 lens. CONSTITUTION:The titled lens is of 3 groups X 3 lens construction. Where (f), f1, ri, and di denote the focus distance of the overall distance, the focus distance of the 1st lens, the radius of curvature of the i-th lens plane from the object side and the plane interval of the i-th lens from the object side, respectively, inequalities (1)-(3) are satisfied. If f/f1 exceeds the upper limit given by inequality (1), an image surface becomes excessively positive. Whereas it exceeds the lower limit, Petzval sum becomes too large to be corrected. In terms of inequality (2), the spherical aberration or the curvature of the image surface becomes negative when (r2+r3) exceeds the lower limit, and when it exceeds the upper limit, either of them becomes too positive to attain balance. In terms of inequality (3), the aberration is hardly corrected, and thickness becomes too thin to be machined, when d1+d2+d3 exceeds the lower limit. Whereas it exceeds the upper limit, transmissivity drops, and moreover the full length of the lens becomes longer, which prevents compactness.

IPC: G06F17/30
Filed: 1988-07-08
Abstract: PURPOSE:To shorten a retrieving time and to freely add or delet items by collecting the data on a single item into a data file. CONSTITUTION:A file control part 2 is prepared together with a control file part 3 and a data file part 4. A group data producing part collects data for each item and produces the group data for each item. Then the part 4 files each group data obtained by said data producing part into a magnetic disk device. The additional new items are added to the group data which are already collected and registered. At the same time, one of these group data is selected in response to the due retrieving command and the data are retrieved out of the selected group data. Thus the data are extracted in response to the retrieving command. As a result, the data retrieving time is shortened and the items can be freely added or deleted without rearranging data.

Title: Automatic steering system for ship
Inventor: YAMADA HIDEMITSU
IPC: G05D1/00
Filed: 1987-07-07
Abstract: PURPOSE:To aim at stabilizing steering control operation by changing an adaptive gain of a controlling and computing section in accordance with the output of an azimuth deviation judging section so that when the result of output of an external disturbance estimating output section exceeds a predetermined value, a model regulation adaptive control is interrupted. CONSTITUTION:An azimuth deviation judging section 7 judges whether an azimuth deviation epsilon exceeds a threshold value epsilon0 or not, and it is below epsilon0, a gain corresponding to an error (e) of an adjuster 4 is reduced. Further, if the above-mentioned azimuth deviation epsilon dose not exceed the threshold value epsilon0 for a predetermined time period, the operation of a model regulation adaptive control 5 is stopped. Further an external disturbance estimating section 8 estimates the level of external disturbance 6, and if the S/N ratio is worse as in a storm weather condition, the operation of the model regulation adaptive control 5 is compulsorily stopped through an external disturbance level judging section 9 and a change-over switch 10. Thus, it is possible to stably operate the model regulation adaptive control 5 irrespective of automatic course keeping operation and of a storm weather condition, and further, it is possible to restrain the yawing width below an estimated value due to a suitable adaptive gain.

     CONSTITUTION: A crane 14 is used to lower the hanger 12 installed at the center of a stopper supporter 4, and the stopper body 1 is inserted in the major axial direction of the oval opening 16 of a hot-metal mixer car 15. Then, the crane 14 is horizontally rotated by 90° to position the body 1 on the minor axis of the opening 16. This makes both the longitudinal directions of supporter 4 and car 15 in parallel each other. At this position, the crane 14 is lowered to attach the supporter 4 on the hooks 13, then the crane 14 is removed to attach the body 1 to the car 14. Next, the car 15 is tilted to cause hot metal 17 to flow out. At this time, the body 1 floats on the hot metal 17 in the car 14 and prevents slag from flowing outside. After use, the body 1 is removed in the reverse procedures of charging and is repeatedly used.

Abstract: PURPOSE:To move a similar stable point to a control stable point quickly by providing a means which decides the polarity of the differential frequency between a playback pilot signal and a reference signal and a means which varies the frequency of the reference signal determined for each head. CONSTITUTION:When the output of a head A, for example, is processed as a playback video signal, a signal generated from a pilot signal reproduced by the head A is selected by a switch 40 and an inverting amplifier 15a and a switch 16a are used to supply a tracking error signal to a capstan servo circuit. A switch 41, on the other hand, selects the output pilot signal of a head B which traces a position leading the switch 40 by one-third as much as one track. The selected signal is used by an inverting amplifier 15b and a switch 16b to generate a tracking error signal, which is supplied to a comparator 21. Thus, the outputs of the adjacent heads are utilized to detect a stable point and the similar stable point only by deciding the polarity simply.
